s on fc3s forum under the tbmod the guy said by plugging the vacum hose on the double throttle atuator, i will simulate what the engine will run like after taking the double throttle butterfly plates off. is this true or am i just blocking up one of the throttle valves?


oh ya, and is there any performance gain in removing the acv or is that just for space and emiss. redux?

 

anybody?>

 

On an NA, it's mostly to simplify the TB & make it easier to work on..

On a turbo the secondary double throttle opens slowly all the time, even after warm up.
So removing it helps throttle response.

 

And if you're gonna go that far(if you have a turbo) you may as well take the ol dremel tool and port/polish a little.

 

Is that why my TII is really jumpy when trying to cruise? it has tb mod done, and i have to eeeease into and outof the throttle to avoid a mild whiplash, lol

 

It probably contributes to that problem. But on the other hand both my 7s do that too, to an extent, and i chose not to do that mod cause i think it is bad enough and i didnt need any more throttle response. You do learn how to drive so you can avoid the jerking when going over parking lot speed bumps and ****. Most older manual sports cars i've driven are the same way the 7 is pretty bad tho. I wonder if my turbo will get worse once i get a better clutch.

These cars just werent meant to go slow.
